Answer: Brielle will run the marathon faster.
Brielle = 104.8 minutes
Joshua = 157.2 minutes
Step-by-step explanation:
Speed rate = distance /time
Brielle = 1.25 /10 = 0.125 miles per minute
Joshua = 1.5/18 = 0.083333 =1/12 miles per minute
Since 0.125 (Brielle) > 1/12 (Joshua)
Brielle will run the marathon faster.
To calculate the time that takes each one to run the entire race (13.1 miles)
Time= distance / speed
- Brielle = 13.1 /0.125 = 104.8 minutes
- Joshua = 13.1 / (1/12)= 157.2 minutes

Answer:
-4/5
Step-by-step explanation:
Two points that I see are not decimals are (-3,1) and (2,-3)
y1-y2/x1-x2= slope
-3-1/2-(-3)= -4/5
The surface area of a prism is the sum of the lateral area plus the area of the two bases.
<span>LA = p * h </span>
<span>p is the perimeter of the base </span>
<span>For your prism </span>
<span>SA = 2(70) + 50 * 9 = 590 mm^2 <-----OPTION C
